The way that i learned this was first set > to = worry about it later

so 9x-7i=3(3x-7u)
so 9x-7i=9x-21u
the x cancel out
so 7i= -21u
now isolate the variable
so
7i/-21=u
so
u=-i/3

The lines represented by the equations y=x+5 and 2y-2x=10 are
ioda

The equations representing the lines, y=x+5 and 2y-2x=10, have the same slope, therefore the lines are parallel.

<em><u>Recall:</u></em>

  • Two lines that are parallel will have the same slope value.
  • Two lines that are perpendicular to each other will have slopes that are negative reciprocal of each other.
  • Equation representing a line in slope-intercept form is: y = mx + b, where m is the slope.

<em><u>Given:</u></em>

y = x + 5

2y - 2x = 10

The slope of y = x + 5 is 1.

Rewrite 2y - 2x = 10 in slope-intercept form to determine its slope.

2y - 2x = 10

2y = 2x + 10

  • Divide both sides by 2

y = x + 5

Thus, the slope of y = x + 5 (2y - 2x = 10) is also 1.

The equations representing the lines, y=x+5 and 2y-2x=10, have the same slope, therefore the lines are parallel.
